To all ivkom it may concern;

citizen of the United States, residing at Provincetown, in the county of Barnstable and State of Massachusetts. have invented certain new and useful Improvements in a Stud-Bolt Tol,-ofwhich the following is .se'rting'or remo'ving the stud 'bolt withouta specification.

This invention relates to improvements in tools and has for its principal object to-provide a simple and eflicient means for instripping the threads vthereof.

- In the accompanying drawing forming a' the device is rendered in its-operation.

A further object is to provide a tool of the above mentioned character,- which is simple -A. further object of 'the invention is'to placed'in position on'theouter end of a stud bolt, means being associated therewlthg for 1prreventing the disengagewent of thesleeve om the outer end of'the stud boltjso that positive and efiicient in construction; inexpensive; strong and du-v rable and furthermore adapted for the purposes forwhich 'it is designated. Otherobjects and advantages of thisinve'ntion; will become ap arent during the stud'bolt 1. A hexagonal head "8. is associated with the outer end of thebolt 6 for .facilitatingthe securing of the same the upper portion of the sleeve.2.

In securing a stud bolt in place' the threads of the stud bolt oftentimes becomes stripped or otherwise da na ed so that when the stud bolt is removed from 'its su port, the same; is of no further use. In or er that a stud bolt may be'properlydriven in place without damaging the threads thereof, I
